Mercedes Fuel Drain

ABOUT

Filling Diesel in a Petrol Mercedes is a well-known problem. And its remedy depends upon a few factors. If you would like to know what you have to do to fix it then read on.
Right here are the key factors to take into consideration whenever determining whether to get the car drained:

  1. What level of Diesel have you put in the Mercedes, bearing in mind that the fuel tank capacity of the Mercedes SLK 350 is in most cases about 70 litres?
    1. A tiny quantity of Diesel, something like 3.5 litres of Diesel in a Petrol SLK 350 will in most cases not really be a massive problem. Experience has proven to us that quantities less than 3.5 litres (almost 5% of the total fuel tank) is very often able to be sufficiently diluted simply by completely filling the rest of the tank with Petrol.
      It's relatively uncommon to find a vehicle experiencing problems due to below 5% wrong fuel contamination. Keep in mind that it is unusual - not impossible to find. You can get a few cars that don't endure any level of fuel contamination in the slightest.
    2. Somewhere between 3.5 and 7 litres of Diesel in the Mercedes (5 to 10%) is more of a 50/50 situation. Our experience demonstrates that as many people get away with it as all those who break down. When deciding whether or not to chance it and just top it up remember that it is exactly like betting it all on black - you've got a 50/50 possibility of it being ok.
    3. Anything over 7 litres of Diesel in your Petrol SLK 350 ought to as soon as possible be drained as your probability of succeeding with this amount of contamination is more than likely below one in 50 - really big odds.
  2. Put some Diesel in a Petrol Mercedes and drove it: Have you spotted any kind of performance issues after putting the bad fuel in your SLK 350? If that's the case, get it drained regardless of the amount of Diesel or even the contamination percentage. Continually running an automobile that is now beginning to suffer the effect of fuel contamination can likely bring about even more harm being done to your fuel system components.
  3. Are you looking for reassurance?
    Simply get it drained. Regardless of contamination percentage, there is inevitably a certain level of risk associated with operating a Petrol motor on Petrol contaminated with Diesel. Likely implications of driving on the wrong fuel include the motor refusing to start, running unevenly, loss of power, degradation of the high-pressure pump, damaged or bunged injectors, etc. These are several of the most typical Diesel in Petrol warning signs, and if you detect any of them then stop driving and have it removed as soon as possible.

Diesel in Petrol Questions

When someone has put Diesel in a Petrol car they have a few very common questions. So we have compiled a list of the most Frequently Asked Questions for you

I put Diesel in a Petrol car and drove it. What do I do?

Answer

Turn off the car as soon as possible and call us. Continuing to run a vehicle on the wrong fuel can potentially damage it. We will be able to give you advice and assistance based on your circumstances

Will driving a Petrol car on Diesel cause damage to it?

Answer

It can. However, if the problem is caught and remedied quickly the risks will be minimal. Of the 1,500 vehicles we attend every month, less than 0.5% have suffered and substantial damage requiring parts replacement.

How much Diesel can I get away with in a Petrol car?

Answer

The safe answer is none. However you might be able to get away with a very low contamination ratio. That being said, we always highly recommend draining anything over a 5% contamination ratio asap.

I know about petrol in diesel, but what about Super Unleaded?

Answer

Putting Super Unleaded, or Shell V-Power, BP Ultimate Unleaded, etc, will have the exact same effect as putting regular unleaded petrol in your diesel car and will need to be drained out and flushed.

Will getting you to do a fuel drain void my warranty?

Answer

No! The EU Block Exemption Regulations clearly state that "the work can be carried out by as long as that garage uses manufacturer approved parts and correctly follows the manufacturer's service schedule."

Can I top it up with Petrol and add some 2-stroke oil?

Answer

This might work on some vehicles in some cases, but in the majority on instances it won't and you risk damaging the Lambda sensors as well as fuel pump and injectors, just as a regular misfuel.
